WILLIAM H. TRACY, OF HOLLAND, KENTUCKY.

COMBINED CLOD-CRUSHEB AND SCRUB-GUTTER.

Application filed August 31, 1916.

To all whom it may concern:

Be it known that 1, WILLIAM H. TRACY, a citizen of the United States,residing at Holland, in the county of Allen, State of Kentucky, haveinvented a new and useful Combined Clod-Crusher and Scrub-Cutter; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same This inventionrelates to a combined clod crusher and scrub cutter, and one of theobjects of the invention is to provide a device of this kind which issimple, etficient and practical in construction.

Another object of the invention is to provide a device of this kindconsisting of a frame constructed in two sections hingedly united, therear section of which has a plurality of clod or scrub cutters, and isadapted to be thrown upon the forward section, to hold the scrub cuttersout of operation.

Another object of the invention is to provide yieldable supporting meansforithe rear section, when folded upon the forward section.

Another object of the invention is to provide a plurality of barspivoted transversely of the rear section, each carrying a series of clodand scrub cutters, each of which bars is adapted to be inverted, so asto hold the cutters out of operation, either when the rear section isfolded or is thrown down to drag at the rear of the forward section.

In practical fields the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts ashereinafter set forth shown in the drawings and claimed.

In the drawings 1-- Figure 1 is a view in perspective of the improvedclod crusher and scrub cutter con structed in accordance with theinvention.

Fig. 2 is a longitudinal sectional view on line 22 of Fig. 1.

Fig. 8 is a sectional view showing the rear section folded.

Fig. A is a sectional View on line 44: of Fig. 2.

Fig. 5 is a sectional view on line 55 of Fig.

Referring more especially to the drawings 1 designates the frame as awhole of the improved clod crusher or scrub cutter, which Specificationof Letters Patent.

frame consists of the forward and rear sections 2 and 3, which arehingedly united by means of the transverse rod 5 and the eyes 6 of theplates 7 which are secured at 8 to the sections. The sections consist ofthe side runner members 9 and 10. The sides 9 are connected by thetransverse bars 11, the ends of which are counter-sunken in the sides 9,there being angled bars 12 for holding the bars 11 to the sides.Connecting the bars 11 is a central bar 13. The bars 11 arecountersunken into the under face of the bar 13, while the bar 18 iscountersunken in the upper faces of the bars 11, there being suitablebolts 1 1 connecting said bars. The bar 13 is additionally bracedrelative to the forward bar 11, by means of the angle bar 15. A suitableequalizer (not shown) may be connected to the forward extremity of thebar 13 whereby the machine may be drawn over the soil. Secured upon theunder portions of the sides 9 are the runner plates 16. Referring to therear section it is to be seen that transverse bars 17 have their endscountersunken in the upper edges of the sides 10, there being metalstraps 18 bolted to the bars 17 and the sides 10 to insure a rigidstructure. Connecting the bars 17 and countersunken therein is a centralbar 19. A bolt 20 extends through the rear end of the bar 19 and therear transverse bar 1'? thereby connecting the two bars. Secured by abolt 21 and a bolt 22 is a supporting spring mem- 381 23, which iscarried by the bar 19, so that the spring arm 24 will engage the bar 13when the rear section is folded in an inverted position upon the forwardsection, thereby holding the cutters or their carrying bars out ofengagement with the ground. The bolt 22 passes through the forward bar17, and the central bar 19, thereby additionally reinforcing thestructure. Bolted to the rear upper surfaces of the sides 10 are handle.

members 25, whereby the operator may fold the rear section upon theforward section. Arranged from one side 9 to the opposite side 9 arethree bars 26, which in cross section, as shown in the drawings aredisposed angularly. Secured upon the front faces of the bars 26 at theirend are angular plates or straps 27, which are bolted at 28 to theadjacent faces of the sides 9. In the rear of the bars 26 are abutmentplates 29, which are carried by the inner adjacent faces of the sides 9,to reinforce the bars 26. Wear plates 30 are bolted upon the bars 26,with which the clods and the like contact, thereby preventing wear uponthe bars. The plates are angular in cross section, so as to fit thecorners adjacent the under edges of said bars 26. Arranged transverselyof the rear section are the transverse bars 31, the opposite ends ofwhich are provided with angular straps or plates 32, which are pivotedupon bolts 33 to the inner faces of the sides 10, whereby the bars 31may be arranged in different adjusted positions pivotally, so that thebars 31 may be disposed as shown in Fig. 2 in contact with the abutmentplates '34-, which are carried by the inner faces of the sides 10. It isto be seen that the bars 31, each carry a series of cutting knives 35.Each knife consists of a single piece or strip of metal twisted uponitself as shown and bolted at 36 to the bar. It is to be seen that whenthe bars 31 are disposed as shown in Fig. 2, the knives are arranged ina rearward direction, so as to bury deep into the soil, for cutting andchopping the clods and the like. However, when the rear section isthrown down, in order to drag at the rear of the forward section, asshown in Fig. 2, the bars 31 may be moved upon their pivots, so as todispose the cutting knives in an upward and forward direction, and outof operation, whereby the bars 31 may drag on the soil. This particularmanner of disposing the bars 31 is particularly used when the rearsection is folded in an inverted position upon the forward section,thereby holding the knives in suchwise as to prevent injury to the handsof the operator. Secared to the outer faces of the sides 9 are hinges37, the pivoted leaves of which have slots 38, to receive the staples 39of the outer faces of the sides 10, there being hooks l0 rear sectionmay be folded upon the forward section and a spring support carried bythe upper face of the rear section to engage the forward section, tosupport the rear section when folded, and of means for latching the twosections, whereby the rear section may drag rigidly .in the rear of theforward section, a plurality of drag bars connecting the sides of eachsection.

2. In a clod crusher and scrub cutting machine, the combination of aframe consisting of two sections hingedly united, whereby the rearsection may be folded upon the forward section and a spring supportcarried by the upper face of the rear section to engage the forwardsection, to support the rear section when folded, of means for latchingthe two sections, whereby the rear section may drag rigidly in the rearof the forward section, a plurality of scraper bars connecting the sidesof each section, means for pivoting the scraper bars of the rearsection, abutment means for the pivoted scraper bars, and knives carriedby said pivoted scraper bars.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 7
